Description

[0001] When this type of procedure is attempted, there are static machines available, which are very costly and complicated. The object of the present invention on the contrary, is a light, easy to operate machine, which can be used on sites and in places that are hard to get at. The procedures must therefore be simple and effective and there must be no possibility of the parts that comprise the whole, becoming detached.

[0002] In the case of machines of this light type, no efficient machines are known.

[0003] An explanation of the machine is given below, referring to the arrangement of the parts it is comprised of.

MAIN BODY (1).

[0004] The holder -7- is an integral part.

[0005] - It has a crosswide partition -3- in the shape of a fork where the part -26- is lodged.

[0006] - It has the spin axis -8- around which the second holder -10- rotates and also serves to rotate the pinion -9- that rams the toothed rack -14-.

[0007] - It is prolonged in a casing -2- in a "U" section that forms the housing -29- inside, where the piece -13- can slide, which is cut in the shape of a toothed rack -14-

[0008] - On this casing -2- and therefore locked into the whole of the general casing -1- there is a semi-cylindrical seating -5- that has ears -31- where an axle -32- is fixed to permit the other half of the clasp -6- to be lowered.

[0009] - At the side of this casing -5- it has guides -36- which permit the piece -37- to be slipped by thrust of the cam -39- which is linked to the lever -42-.

[0010] - When the piece -37- is shifted, the peg -35- which is linked to the part -6- is dragged along and a stable grip is made.

MOBILE BODY (13).

[0011] - Which has the toothed rack -14- on one of the sides.

[0012] - Which has the plate -15- at one end.

[0013] - In this said plate -15-, in the space -20-, the piece -21- is lodged which will be held by the stubs -4- and the tension of the spring -17-.

[0014] The Machine works as follows:

[0015] Bringing together and separating the two lever arms -7- and -10- according to the position of the latch -12- which turns on the point -11-, the pinion -9- is made to turn in one direction or another. By this turning of the pinion -9-, the piece -13- is dragged along, since the pinion is locked into the toothed rack -14-.

[0016] This movement determines whether the sheets -15- and -3- are brought together or separated and consequently determines coupling of the bodies by simple axial pressure.

[0017] For the frontal support of one of the pieces to be connected, the part -21- has been provided, which is quickly lodged and held in the housing -20- where it is gripped.

[0018] The other part to be connected is held by the holders -5- and -6- which are brought together by simply turning on the axis -32- after the peg -35- has been placed in the groove -43- by turning of the lever -42- as per F gripping is made quickly and effectively.

[0019] This part held thus, also has an intermediate support point in the piece -26- which can be placed in the forked part of the sheet -3- where it is held firmly thanks to the stubs -4- and the spring -17- which it has on one of its sides.

[0020] With regard to the state of the above technique, the machine proposed by the invention offers the following advantages:

[0021] Quick gripping by means of the type of holder -5- and -6- and the operating lever -42-, of one of the pieces it is desired to connect.

[0022] Quick gripping of the parts -21- in the fork -15- and of the part -26- in the fork -3-.

[0023] But besides quick gripping, the gripping is stable and permits the machines to be used in all sorts of positions, with no danger of the auxiliary parts becoming detached.

[0024] Besides quick gripping, it must be pointed out that the separa­tion of the pieces held, for substitution, is also done easily and quickly since this is the opposite operation.

[0025] A more complete idea of the invention is provided by the follow­ing description in which reference is made to the enclosed sheets of draw­ings which represent the whole and preferred details of the invention.

[0026] In the drawings:
Figure 1 corresponds to an elevational view of the whole of the machine; it is the position it adopts at one moment such as for receiving the bodies that have to be joined together axially.

[0027] In this figure the fundamental body -1- is shown clearly which in the lower part has one of the driving levers -7- interlocked and in turn has the spin axis -8- where the second holder -10- is articulated.

[0028] This fundamental body -1- is prolonged upwards in one direction in a sheet -3- with the shape of a fork, where the supplementary parts -26 - will be held if advisable, which will serve as a support for one of the pieces that have to be joined axially.

[0029] On the other side it is prolonged in a body -2- that comprises a guiding housing -29- where the piece -13- will be slipped cut in the toothed rack -14-.

[0030] This same body has a semicylindrical housing -30- interlocked in the body -5-, on which one of the pieces it is desired to connect is placed. Having a fixing device that acts by means of a lever -42- which by means of a cam determines the descent and gripping of the part -6- which serves as a clasp.

[0031] Besides representing the main body, in this figure the part -13- can be seen which can be shifted as soon as the arm -10- is made to rotate so that the pinion -8- acts on the toothed rack -14-.

[0032] This part -13- likewise ends in a sheet -15- in the form of a fork, between the branches of which the supplementary piece -21- will be lodged.

[0033] The supplementary piece -21- is lodged in the fork -15- following the placement movement -B-. Then a turn is made in same as per -C- and it is clamped in a stable position. In the same way, the supplementary part -26- will be lodged in the fork -3- introducing it between its arms as per -A- to achieve the same hold including spring, by means of rotation, as holding of the piece -21- already mentioned is made.

[0034] Figure 2 serves to represent the whole place -21- which is the one that will be lodged in the fork -15-. The outline of the place -24- of this piece will be suitable for one of the pieces it is wished to join axially by means of the present machine.

[0035] Figure 3 serves to represent the whole of piece -26- which is the one that will be lodged in the fork -3-. The outline of the housing -28- as well as its size will depend on one of the pieces it is desired to join axially by means of the present machine.

[0036] Both piece -21- which will be held in the fork -15- as well as piece -26- which will be held in the piece in the form of a fork -3-, will be introduced by simple thrust and will be rotated as per -C- to be positioned in their corresponding housings in a stable manner.

[0037] Figure 4 is a view of the forked part of the end of the part -13-, which is where the part -21- will be lodged. It can be seen that it has a spring -17- which will make the fixing stable because of its tension.

[0038] Figure 5 is a view in which is represented the way in which the part -21- is left stable.

[0039] In the same way in which the part -21- is held, the piece -26- is held in the fork -3- that also has the spring -17- and the limiting stops -4-.

[0040] Figure 6 is a flat view. The quick holding device shows the two parts of the semicylindrical housing -30- the lowered part -6- with the other semicylindrical one -34-.

[0041] Lowering is made around the axis -32- and the elevational posi­tion is represented in figure 8.

[0042] Figure 7 is a flat view when the part -6- is already lowered down onto the part -5- and ready to hold a possible piece -44-.

[0043] This elevational arrangement is seen in figure 9.

[0044] Figure 8 is a cross section of a section of the machine showing the quick holding arrangement it has, opened out.

[0045] It shows the way that any piece -44- can be placed,simply placed in direction -D- on the cavity that the piece -5- forms, so that, the piece -6- will happen to cling to the piece -44-, making it then rotate on the axes -32- as per -E-.

[0046] Figuee 9 is a similar view to the previous one, when the piece -6- has been rotated, lowered on -5-.

[0047] Figure 10 is an elevational view, after the piece -6- has slid on the axis -32- until the peg -35- linked to the piece -6- has been introduced in the groove -43- of the piece -37-.

[0048] It is after taking up this position, when the lever -42- is moved as per -F- , when by the action of the cam -39- lodged in the window -45- of the piece -37- it makes this descent, until the necessary holding pressure of the piece -6- against the piece -44- that it is wished to hold is substantiated.

[0049] Figure 11 is a section drawing that shows the way in which the piece -37- has descended by the action of the cam -39-.
